Flooded Basement Drywall Repair

basement construction

Basement floors often get flooded and damage the drywall on the basement. The drywall gets ruined by moisture and mold, usually on the lower section of the drywall.

Instead of tearing out the whole drywall to rebuild it, we can help you permanently repair the damaged parts on the lower section. DMV Drywall repair team will help you replace the damaged materials with more durable ones to protect your drywall from future damages.

Things to know before repairing flooded basement drywall

The flooding that has caused wet drywall may lead to the ceiling collapsing. Always be on the watch for your own safety.

If the flooding was caused by plumbing issues in your home, it is important to first locate the water source and resolve it before repairing the drywall.

How to repair flooded basement drywall

The first step is to remove the water within 48 hours from the time it soaked. A quick response to dealing with the water will prevent additional damages to your furniture, floor, and drywall.

Safety first

When removing the drywall, always wear respiratory protective equipment since some drywall types contain harmful asbestos. Switch off the electric power supply system and remove non-affected electric systems before tearing out the drywall.

Remove damaged drywall parts

Decide on the length you are going to cut off. If the water, for instance, only damaged the drywall by three feet, cut off the drywall up to four feet.

You can also inspect the drywall if you are unsure of the level that has been damaged.

Cut the damaged parts

Mark a straight line for easier cutting along with the drywall. You can use chalk or any other marker that can be effective.

Cut along the line using a knife and carefully remove the damaged part carefully. After removing the damned part, take out all the insulation materials from the drywall that has not been damaged. The insulation materials may look fine but it is likely damaged. You can leave them to dry for some time.

Dry the damaged walls

You can use dehumidifiers to dry both the inside and around the drywall. Leave fans running in the room for better airflow for at least 48 hours. It helps to dry the studs and the flooring.

Apply chemical sanitizer

In order to prevent mold and bacteria from forming in the future, use chemical sanitizers. Also, use deodorants to remove the odor. Leave an ozone machine running for a minimum of eight hours.

Replace the damaged drywall

Measure the size to be replaced and how much should be cut from the new piece of drywall. Put drywall clips around the space and secure them with screws. Use tape and joint compound to blend it with the old drywall. Sand the area for a smooth surface.

Paint the restored drywall

After the joint compound is dry, paint the wall to seal it and for uniformity.


Types of Basement Floor Drains

Basements are rooms or spaces beneath the house, and they absorb water that drain from the above rooms. The inbuilt house drainage does not eliminate flooding possibilities and may not prevent water from seeping through the basement. Homes without proper basement drainage puts the house at risk of water flooding in the basement. This may cause havoc even to the structure of the building.

If you are building a house or a home, it is better to know your waterproof methods or deal with water problems. Here are some of the types of basement floor drains to help you keep the water drain properly without any effects.

Exterior Drain Tile

Exterior drain tile is installed around the outside of the perimeter of a foundation. This type of drain is more effective, and it collects groundwater before it can penetrate your basement. A drainage pipe is placed around the bottom of the walls during the construction of the foundation.

The exterior drain tile is not expensive to install during the initial construction. It can be accessible in case of repair and cheap to maintain. The exterior drain tile drains water away from the foundation to make it not penetrate the basement.

When installed after the house is constructed, it is so costly compared to being installed during the foundation. The sand must be removed deep enough to the footings. The cost of installation depends on the size of the foundation before the drain is installed.

The disadvantage of this drain is that it may clog or block over time if the contractor does not use fine gravel during installation.

Interior French Drain

The interior french drains are commonly used when basement water problems start to appear in existing homes. The interior french drain has a perforated pipe that drains water to a collection tank for reuse.

The interior french drain is located on the basement’s interior perimeter and lies below the floor level. The pipe must be surrounded by the gravel keeping the mud particles from penetrating. The trench is essential to containing the drainage pipe and the stone.

The cost of installation during basement construction is sufficient; a minimal amount of money will be added to the foundation bill. This does not support water clogging. The water is directly collected and channeled to a pit via a sump pump where it will be used for other purposes.

The whole process of installation of interior french drains is tiresome. Drilling down and breaking the floor area is hectic and expensive, depending on the floor area.

Floor Drains

The installation of floor drains done during the actual construction, used to drain away from the basement. The floor slopes gently towards the drains and goes out. The old constructed homes, drains were channeled into the sewer lines. This was risky because, in case of sewer clogging, the water may get back to the basement.

The disadvantage is that the floor drain will allow water back to the basement in case of clogging.

Conclusion

Basement drains are essential in your house or home. To eradicate water clogging and stagnation, you have to choose your preferred and pocket-friendly drainage system. A well-installed basement drain solves your water drainage problems.


Waterproofing Techniques For Terrace

Terraces is one of the tricky parts when it comes to construction. The surface is flat and it becomes hard for water to run off the structure. When water moves slowly or stagnates on the terrace, it can be dangerous for the whole structure, weakening it and causing leakages. Knowing waterproofing techniques for terraces can help you avoid this problem for your building, making it durable. Here are some waterproofing techniques for terraces to help keep your house dry and free from leakages.

Traditional Methods

The traditional methods include the brick bat coba method and bituminous treatment.

In the brick bat coba method, the brick and motor are used to make a slope for water to easily run off from the flat terrace.

The bituminous treatment uses (asphalt) as a thin layer on top. Both these traditional methods involve the addition of waterproofing chemicals  to the mixtures.

Modern methods

A waterproofing layer is formed by mixing chemicals and cement. However, this is not a favorite choice to many as there are poor quality chemicals circulating around with short shelf life and vulnerable to extreme weather conditions.

Terrace Waterproofing Procedure

Preparation of the surface

Remove loose concrete and debris on the terrace by raking the construction joints before patching the joints with cement and sand mortar.

Grout the nozzles and clean the RCC substrate to remove any oil, grease, and loose particles.

If there are any cracks on the RCC, repair them with cement-sand mortar.

Coating

Use a sprinkler water to wet the RCC and apply two coats o f cement based polymer. The two coats should be applied at the right angles. Lay a glass fiber mesh between the two coats for additional tensile strength. Add a third coat when the second coat is dry.

Protective Layer

Add a protective layer made of cement and sand mortar mixed with a waterproofing compound.

Brick Bat Coba Treatment

Lay brick bats with at least 40mm thickness to a specific slope. Apply the cement sand mortar mixed with a waterproofing compound on the voids left by the brick bats.

Apply 20mm thick joint less waterproofing plaster and finish the surface with a coat of neat cement. Make khurras for drainage off the terrace. After the whole process, cure the whole surface with water for two weeks.

What To Consider Before Waterproofing

It is important to consider certain conditions in order to choose the most appropriate waterproofing solution. Before waterproofing a surface, here is what you should consider.

  • Evaluate the state of the flooring
  • Verify the layered part of the structure
  • Ensure that the slope of the floor is appropriate
  • Make sure there is no separation or cracks between the layers.

Depending on the condition of the terrace, you can choose the suitable option for waterproofing.

If there are any issues found, such as cracks and holes, it is important to repair them first before waterproofing the terrace.

Conclusion

Terraces are a very important part of any building. They provide additional space to keep equipment, and lso offer room for expansion of the building. Keeping them in good shape by waterproofing can help maintain the overall structure of the building. Waterproofing helps in preventing leakages and thereby keeping the structure dry and strong.
