How To Seal Your Foundation In New Jersey
Ensure your contractor is aware of local building code for a properly sealed foundation.
The process of foundation sealing varies across the country, thanks to differences in soil composition, annual rainfall and yearly temperatures. In New Jersey, building code requires that waterproofing is accomplished by placing a membrane under the slab. This can be made from rubberized asphalt, butyl rubber, polyvinyl chloride with joints or polyolefin composite membrane.
Reputable local contractors will have extensive knowledge of these requirements and will work through proper steps to ensure your foundation will last a lifetime. Depending on the soil, moisture and gasses can be prevented through construction techniques like a special mastic coating and drain board on the exterior of the foundation wall.
In new construction, drain tile is installed at the foundation footing to redirect water away from the house. Before pouring your basement floor, gravel fill is used beneath the slab with a poly membrane to resist moisture and gasses released from the soil.

If executed properly, these modern techniques will prevent cracks or gaps in the foundation. Problems can come into play, however, in older homes. This can be thanks to obsolete building techniques or prior owner neglect. If you have a historic house, there are some warning signs to look out for. Keep your eyes peeled for any cracks in the foundation, sloping floors, or misaligned doors and windows. This can suggest a structural issue that requires immediate attention.
If you spot any of these red flags, hire a structural engineer on HomeAdvisor to help. Don't try to seal cracks or gaps on your own or with the help of a handyman before a professional diagnosis. You might make the problem worse by obscuring the issue. A structural engineer isn't going to repair the damage, but they are best equipped to diagnose the program and advise how to properly resolve it.
