"Dave with 2 other workers were prompt and efficient. They came when they said they would and finished everything in 2 days. Everything looks fantastic because they protected my personal space with a plastic shield and cleaned everything up. Dirt and rubble was hauled away and they even sprayed my walkways outside. They installed the basement system and connected all my outside downspouts. I would highly recommend Highlander to anyone who needs waterproofing because they went above and beyond to make sure I was happy."

"This is the second time we have hired Groundworks (formerly Bakers Waterproofing) to perform work at our house. The first project was in 2017 when we had the waterproofing system installed. We called Groundworks a few weeks ago to get an estimate on lifting our front sidewalk and stairs that have sunk a lot over the past year. The steps had sunk to the point that the railings were not connected to the house, making it very unsafe for anyone coming into the front of our home. Aaron Lenker & Corbin Gillichbover were very professional and knowledgeable when they arrived to assess our sidewalk and steps to lift them. They left our sidewalk and the surrounding area better than when they arrived. Our steps and sidewalk are now level, and the railings are securely attached to the house again. We are thrilled! I would highly recommend Groundworks if you need a basement waterproofing system or any concrete lifted."

Basement Waterproofing questions, answered by experts

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.
