LUX Foundation Solutions is a fully licensed and insured foundation repair, waterproofing, crawlspace repair and masonry service contractor. Providing services to a large part of central and Northern Virginia. With Combine Experience of over 25 years!

"Very, very disappointing experience; Lux replaced the foundation of my 1850 log cabin. The design was bad, the communication was bad, the execution was bad. Throughout the entire process, they were making mistakes. I now need to pay another company to fix the mess they left behind. I would strongly suggest not using this company!"

Exterior Waterproofing Experts is a Class A General Contractor in the state of Virginia since 1997. Our service protects your home against wet basements, water leaks, flooding, water seepage, foundation leaking, and wall seepage. We have been doing subcontract grading and drainage work for many years. We have completed many waterproofing contracts for residents of Fairfax County, including: Fairfax, Alexandria, Arlington, McLean, Great Falls, Potomac, and Vienna, Virginia (VA). We are now offering to work directly for clients, passing the savings on to the homeowners. It is our belief that water problems are best solved from the outside before water gets into your home.

"My basement had mold and evidence of water damage in July/August, and I was referred to Exterior Waterproofing Experts. The majority of the mold was on the side of my house, but the salesperson made a strong pitch about the need to waterproof the front of my home by digging up the garden down to the foundation. My wife was largely convinced, so we went ahead with the $8000 project. Six months later, the insulation behind the waterproofed front of the house is sopping wet. When the salesperson came back to my home to take a look, his explanation was that the water probably came up through the floor. His words were along the lines of "99% of the time the water comes up through the front." At this point, I feel like I have an expensive solution to a problem I didn't really have."

Structural Engineering questions, answered by experts

The process involves initial consultation, concept development, detailed planning, regulatory approvals, and integration of contractor work for project execution.

If your home's foundation was damaged due to shifting soil, the same problem will reoccur unless you stabilize the structure by adding posts in the bedrock.

A 4-inch-thick concrete slab can support around 4,000 pounds per square foot if a contractor reinforces the slab with rebar, while that same slab without reinforcements will support closer to 1,000 pounds. For the purposes of a patio, 4 inches in thickness without reinforcement should suffice unless you’re installing heavy kitchen equipment or a hot tub on it. In those cases, reinforcing your slab and sticking with 4 inches of thickness should provide plenty of strength.

A structural engineer’s report includes a professional assessment of a property’s foundation condition, structural elements like roof trusses and floor joists, and the skeleton of the home, including studs, beams, and rafters. It will also usually include an assessment of drainage on the property and any potential issues that could arise from environmental conditions, like extreme weather in the area and even tree placement.

Clean regularly, treat wood for weather resistance, and inspect for damage to ensure longevity.
