WET BASEBOARD WET DRYWALL REMOVAL WEST GROVE,PA

we care about our customers. We understand the emotional, financial, and physical strains that fires and floods can cause on a person's life. We are here to help you through this difficult time. We will get your home back in order, deal with your insurance company directly, and bring some peace back to these hectic times. 24 hours a day, 7 days a week. If you need us, we are there. Preparing for a flood is very important, but you should also prepare for handling the aftermath of the storm. Flood damage is a like a time bomb, and to prevent mold or structural damage you must do everything you can to quickly and concisely and as soon as possible. To help you learn how to handle this situation, we've put together this list of what to do after a household flood.1. Do Not Re-Enter After leaving the flooded home, do not re-enter until trained emergency workers tell you it is safe. Floodwaters can harm or damage the foundation of your home and make it an unsafe structure to reenter.2. Take Caution When Eating Don't eat or drink anything that has been in contact with flood water. Flood water can and usually does contain unsanitary materials and residue which is not safe to ingest.3. Remove Water Blockage If you put sandbags or other blocks around your home to keep water out, remember they may also be holding water in after the flood. If the structure is safe, open windows, doors, and remove blocks to let some water out. Only approach or touch flood water or flooded areas in proper attire, (gloves, mask, boots, water proof jacket, goggles, etc).4. Flood Insurance If you had flood insurance, don't move or touch anything until you've contacted them. This is because they must come and observe and assess the damage in it's original state. Also be sure not to throw out anything that should be checked by the insurance associates as well.5. Take Pictures As hard as it is, having thorough documentation of the flood is likely to come in handy. Go throughout the home and take pictures of any and all flood-damaged areas. Check ceilings, walls, and floors diligently to make sure you don't miss a thing.6. Watch The Kids! It is imperative not to let children play or touch anything that floodwater has. Even if the floodwater resigns from an area, that area still has infectious bacteria that are dangerous to you and yours. Be sure to sit children down and thoroughly discuss and explain the dangers of floods, floodwater and the aftermath.7. If You Must Leave If for any reason you need to leave your flood-damaged home (to go to a hotel, friends, or get something to eat) be sure to secure the house before you leave. Lock all windows and doors, and try to cover up and holes or unstable structure. Although it's regrettable, looters have been known to target flooded areas for undamaged materials in unsupervised homes. 8.

BUILDING CLIMATE CONTROL FROM WATER DAMAGE OR MOISTURE PROBLEMS (New York, New York)

Richpieriwatwrdamageexpertwww.floodsupport.com 

DRYING OUT BUILDINGS CALL 1-877-71-FLOOD

Excess water content in materialsDehumidification is mainly applied to dry out excess water content in materials in connection with construction work or water damage.

In case of water damage the general rule is to apply dehumidification as soon as possible, but as the nature and extent of water damage varies considerably it is necessary to assess the right approach from situation to situation.

An all important parameter in case of water damage is how much time the water has had to penetrate the building structure, furnishings, etc. It is also essential to keep the air change as low as possible to avoid humid air from entering the room. The Rule Of Thumb it will give you some empiric data to go by as it is often almost impossible to calculate the absolute accurate dehumidification load needed in a water damage situation.

In case of drying out a newly constructed building you should also keep air change low, but the most important parameter to consider is the water content in the various materials used. Often you have to meet a deadline i.e. you have to consider a finite amount of time to do the job.

Drying out buildings call Rich at flood support 1-877-71-FLOOD Formerly construction work on an average building went on for 6-9 months and the building materials were usually dried out by natural ventilation by the time the building was finished. Today, however, construction work is very efficient and much faster. This means that dehumidification is required to remove the excess water in the various building materials before the building can be occupied.

When selecting a dehumidifier for drying out a building you need to consider how much water should be removed and how much time you have to do it.

This is actually quite a difficult task. In some cases it is possible to estimate the amount of water in the building materials from tables. Please note that in regards to drying out a newly constructed building it all comes down to the specific building materials used for walls, floors and roofs. The water content of various building materials differ so much that a simple rule of thumb is unworkable.

Water content of different building materials (kg/m³)

MATERIAL	AT START OF PROJECT	WATER CHEMICALLY BOUND	DESIRED CONDITION AT 50% RH	WATER TO BE DEHUMIDIFIED
Wood	80	-	40	40
Tile, roof	10	-	10	0
Brick, wall	80	-	10	70
Lightweight concrete	100-200	-	20	80-180
Concrete K 15 II	180	42	38	100
Concrete K 25 II	180	57	46	77
Concrete K 40 II	180	71	51	58

In this a Job Done at a local Shopping Center we want to calculate the dehumidification load required to dry out excess water from Storm Damage building in 30 days. The building is 2.4 m high, 7 m wide and 16 m long. The walls and ceiling are constructed from pre-dried wood. The floor, however, needs to be dried out as it is made from 10 cm thick concrete, K 40 II.

The data:

Period	30 days
Drying condition	t = 20°C and 50% RH (average between starting humidity at 60% RH and ending at approx. 40% RH)
Volume of building	2.4 * 7 * 16 = 268.8 m3
Materials	Concrete K 40 II, 10 cm



The calculation:
Concrete volume to be dehumidified:
V = 16 _* 7 _* 0.1 = 11.20 m3

Water content in concrete floor:
Q = 11.20 _* 58 kg water/m3 = 649.6  kg water

We need to remove 649.6 L water in 30 days:
W = 649.6/30 = 21.65 L/24 hours

We need a dehumidification capacity of 21.65 L/24 hours.

Recommendation: CDT 40. Capacity: 0.70 litre/hour at 20°C/50% RH. One CDT 40 will remove 16.8 L/24 hours. This means that two CDT 40 units should do the job.

Note that the drying process is quickest in the beginning as the water content is very high when you start the process. As the RH-value decreases the overall dehumidification capacity will also decrease.

Guidelines for the drying process www.floodsupport.com
When dehumidification is used to dry out buildings and materials the dehumidifier runs continuously. The relative humidity is gradually lowered allowing further evaporation from the damp materials in the room. The amount of evaporation depends on the temperature of the room, the materials and the humidity of the air.

One of the advantages of condense drying is that the drying process is stable and gentle. If time is not of the essence the optimum dehumidification process is achieved by maintaining a stable condition of 20°C and approximately 40% RH in the room. This way you maintain a perfect balance between the dry air in the building and humid building materials, avoiding surface drying and cavitation as well as damage to pre-dried materials such as parquet floors.

Add heat if necessary, but keep in mind that forcing the drying process might be harmful. There is a risk of surface drying and cavitation, with only surfaces being dried, whereas a lot of humidity remains within cavities inside the wall. This prolongs the drying period as the humidity will not easily penetrate the dry surface. Surface drying also involves the risk of cracks appearing in the surfaces of walls, ceilings and floors.

It is important that the room/building is as sealed as possible. Also make sure that the building is well protected against rain and snow. You need to ventilate while painting inside the building, but remember to seal the room or building properly when it is empty. Also remember to avoid pre-dried materials absorbing water because of open windows.

If the air change inside the room is not controlled, then changing ambient temperatures and humidities make the process much more difficult to control. In the winter the cold outside air will normally contain a minimum of water and the humidity is not likely to increase much even if the air change is considerable. Energy consumption, however, will increase dramatically as you need to heat up the cold incoming air. In the summer the water content could be quite high and you will have to remove even more water from the building or locale if it is not sealed off adequately.

In most cases the humidity is concentrated in cellars and in areas where water is being used in the construction work going on i.e. painting, concrete mixing, etc. Set up your dehumidifiers at these positions where they can do most good.richpieribuildingexpertwww.floodsupport.com

Today, however, construction work is very efficient and much faster. This means that dehumidification is required to remove the excess water in the various building materials before the building can be occupied.

When selecting a dehumidifier for drying out a building you need to consider how much water should be removed and how much time you have to do it.

This is actually quite a difficult task. In some cases it is possible to estimate the amount of water in the building materials from tables. Please note that in regards to drying out a newly constructed building it all comes down to the specific building materials used for walls, floors and roofs. The water content of various building materials differ so much that a simple rule of thumb is unworkable.

Water content of different building materials (kg/m³)

MATERIAL	AT START OF PROJECT	WATER CHEMICALLY BOUND	DESIRED CONDITION AT 50% RH	WATER TO BE DEHUMIDIFIED
Wood	80	-	40	40
Tile, roof	10	-	10	0
Brick, wall	80	-	10	70
Lightweight concrete	100-200	-	20	80-180
Concrete K 15 II	180	42	38	100
Concrete K 25 II	180	57	46	77
Concrete K 40 II	180	71	51	58

In this a Job Done at a local Shopping Center we want to calculate the dehumidification load required to dry out excess water from Storm Damage building in 30 days. The building is 2.4 m high, 7 m wide and 16 m long. The walls and ceiling are constructed from pre-dried wood. The floor, however, needs to be dried out as it is made from 10 cm thick concrete, K 40 II.

The data:

Period	30 days
Drying condition	t = 20°C and 50% RH (average between starting humidity at 60% RH and ending at approx. 40% RH)
Volume of building	2.4 * 7 * 16 = 268.8 m3
Materials	Concrete K 40 II, 10 cm



The calculation:
Concrete volume to be dehumidified:
V = 16 _* 7 _* 0.1 = 11.20 m3

Water content in concrete floor:
Q = 11.20 _* 58 kg water/m3 = 649.6  kg water

We need to remove 649.6 L water in 30 days:
W = 649.6/30 = 21.65 L/24 hours

We need a dehumidification capacity of 21.65 L/24 hours.

Recommendation: CDT 40. Capacity: 0.70 litre/hour at 20°C/50% RH. One CDT 40 will remove 16.8 L/24 hours. This means that two CDT 40 units should do the job.

Note that the drying process is quickest in the beginning as the water content is very high when you start the process. As the RH-value decreases the overall dehumidification capacity will also decrease.

Guidelines for the drying process www.floodsupport.com
When dehumidification is used to dry out buildings and materials the dehumidifier runs continuously. The relative humidity is gradually lowered allowing further evaporation from the damp materials in the room. The amount of evaporation depends on the temperature of the room, the materials and the humidity of the air.

One of the advantages of condense drying is that the drying process is stable and gentle. If time is not of the essence the optimum dehumidification process is achieved by maintaining a stable condition of 20°C and approximately 40% RH in the room. This way you maintain a perfect balance between the dry air in the building and humid building materials, avoiding surface drying and cavitation as well as damage to pre-dried materials such as parquet floors.

Add heat if necessary, but keep in mind that forcing the drying process might be harmful. There is a risk of surface drying and cavitation, with only surfaces being dried, whereas a lot of humidity remains within cavities inside the wall. This prolongs the drying period as the humidity will not easily penetrate the dry surface. Surface drying also involves the risk of cracks appearing in the surfaces of walls, ceilings and floors.

It is important that the room/building is as sealed as possible. Also make sure that the building is well protected against rain and snow. You need to ventilate while painting inside the building, but remember to seal the room or building properly when it is empty. Also remember to avoid pre-dried materials absorbing water because of open windows.

If the air change inside the room is not controlled, then changing ambient temperatures and humidities make the process much more difficult to control. In the winter the cold outside air will normally contain a minimum of water and the humidity is not likely to increase much even if the air change is considerable. Energy consumption, however, will increase dramatically as you need to heat up the cold incoming air. In the summer the water content could be quite high and you will have to remove even more water from the building or locale if it is not sealed off adequately.

In most cases the humidity is concentrated in cellars and in areas where water is being used in the construction work going on i.e. painting, concrete mixing, etc. Set up your dehumidifiers at these positions where they can do most good.richpieribuildingexpertwww.floodsupport.com
