The basement in your home may be a viable option for expanding the house's square footage, but if you have water in the basement, finishing the space means waterproofing it as well, or all the work you do could be ruined. Professional basement waterproofing is often the best option to ensure that the basement stays dry after the work is complete.
Before you can start any work in your basement, it is good to inspect the entire basement for any signs of water coming in. A basement waterproofing contractor can be an asset in the inspection because they will know what to look for and notice signs of water infiltration that you might not see. Sometimes small cracks and damage to the foundation or basement walls will go unnoticed for a long time, but when water starts to seep through the cracks, erosion, and damage will worsen if it is not addressed.
Repair and Waterproofing
In most situations, the waterproofing for a basement that is actively leaking should start outside the house. The basement waterproofing contractor working on your home will need to excavate the soil around your basement to determine the damage to the walls and the best way to stop the water coming in. Once the walls are exposed, the contractor can make repairs to the walls, filling cracks and other damage before any waterproofing is applied.
Once the repairs are made to the basement walls, a basement waterproofing material can be applied to the walls and allowed to dry. The material will seal the walls and protect them should other cracks develop over time. The material may need several coats to provide the proper protection, but your basement waterproofing contractor will know how much to apply.
Drainage and Water Prevention
If the basement waterproofing contractor finds a lot of water collecting near your basement walls, they may recommend putting in some drainage around the foundation. Typically some gravel will be added around the base of the walls and a perforated drain pipe put into the hole.
The contractor will add additional gravel or stone over the pipe, creating a system called a french drain. The gravel will allow the water to drain into the pipe, and then the water will drain off to an area away from your home. The drain is not difficult to install, and it can make a significant difference in your basement.
The combination of the waterproofing material and the drain installation can create a dry basement that you can use for just about anything after the job is complete.
