A Quick Guide to the Cross-Drill Injection Process

For many of our clients seeking crawl space repair in Highland Park, Naperville, and the greater Chicagoland area, the most-requested repair is a leak requiring immediate attention. Leaks often stem from cracks, some of which were already repaired (unsuccessfully) before. These are commonly known as “dirty cracks”, of which there are two types:
● A dirty crack that was repaired on the surface but wasn’t injected with sealant. Thus, the surface repair didn’t hold and the leak returned.
● A dirty crack that was injected with sealant, but the sealant failed – whether because not enough was used, it wasn’t applied correctly, or it was of an inferior variety
The first example can be repaired with sealant and surface application. But repairing the second type of dirty crack is a little trickier. That’s why ULB-DRY Waterproofing uses a system called “cross-drill injection” that works exceptionally well. We’re one of the only waterproofing companies using this technique, and we’ve employed it to great effect for many of our customers.
Cross-drill Injection
Cross-drill injection is the perfect solution for homeowners seeking crawl space encapsulation. Being so close to your home’s foundation, any leaks detected must be dealt with swiftly lest they create a bigger problem down the road. Here’s how cross-drill injection works:
● A set of 3/8th-inch holes are drilled within 4” – 6” of the crack. These holes are angled inwards in order to intersect the void at the halfway point.
● Small brass packers, each with a zerk end, are placed securely in each hole
● Once these packers are in place, the void is flushed with cool, clean water
● A one-part urethane grout is injected into the void with a high-pressure pump
● We don’t stop injecting until the urethane grout oozes out of the void, or the back-pressure reaches a certain point. Any material that oozes out is removed once it has hardened.
● With the void completely filled with urethane grout, and with all ejecta cleared away, the entire crack is coated with a flexible, two-part epoxy mastic (a natural bonding agent). The crack is 100% repaired, to the point where you’ll have a hard time believing it was ever there.
● At every step of the process, from preparation to repair to cleanup, health and eco-consciousness are top-of-mind. None of the materials we use are hazardous to the residents’ health or potentially damaging to the environment.
Cross-drill injection is a viable option for repairing a broad size-range of cracks – even ones as narrow as .002 inches. Outside of the waterproofing industry, this technique is used to repair cracks in bridges, dams, buildings, and various other concrete structures. In fact, no less a group than the U.S. Army Corps of Engineers has in their Engineer Manual a “how-to” page concerning cross-drill injection.

Does Your Basement Smell Musty? Water Leaks Can Cause Odd Odors

Of all the rooms in a house, the basement is the one that’s most readily associated with musty smells. Old photo albums, forgotten boxes containing nostalgic odds and ends, a rack of clothes that hasn’t been touched since 1973 – all of these are contributors to the odd odors many basements possess. However, there’s another, far more damaging culprit: water leaks.

ULB-Dry Waterproofing, a long-tenured waterproofing company, knows just how much damage an untreated water leak can cause. But if you get out in front of the problem, you’ll save yourself a lot of time, energy, and money.

Locate the Leak

The leak that’s contributing to your basement’s musty smell is almost certainly due to moisture seeping through your basement’s concrete floor and/or walls. Often times these leaks are created or exacerbated by heavy storms. Search your basement for visible signs of moisture – the most common indicators are damp concrete walls or the presence of a white powdery substance called efflorescence. This powder consists of crystallized minerals indicating the presence of evaporated water.

Take preventive measures

Running a dehumidifier is a good way to minimize the odor and keep your basement’s dampness at bay. However, since mold is the root cause of the odor, you’ll need to don protective clothing and give the affected wall(s) a thorough scrubbing. You’ll also want to clean or discard any musty-smelling furniture, carpeting, clothing, etc., and replace damp boxes with dry ones. It’s also a good idea to invest in storage racks so that you can keep all of your belongings off the floor.

Outside your home, make sure that your gutters are unclogged and that your downspouts aren’t depositing water directly onto your foundation. The downspouts should empty at least six feet from the foundation, on to ground that slopes downwards from the house.

The Pros and Cons of Choosing to Carpet Your Basement

Basements are versatile spaces that can be used for entertaining, as a play space for kids, as a workout room, or a combination of environments. If you’re thinking about finishing your basement or have recently finished your basement, no doubt flooring is near the top of your to-do list. Should you carpet your basement? ULB-Dry Waterproofing, experts in all things basements and basement waterproofing, offers some pros and cons to consider.

The Pros of Carpeting

A carpeted basement conveys a welcoming feel, much like your home’s living room or den. In fact, if you view your basement as a “second living room” or “second den”, then carpet is an excellent choice.

Carpet is a good “sound muffler”, and carpeted rooms are generally quieter than rooms with hard flooring. This is a nice bonus if your basement is split between a kids’ area and an adult’s area.

If you have kids, no doubt they’ll want to carve out their own niche in the basement. Carpet is the optimum flooring choice for children: it’s soft, warm, comfortable to walk on and play on, and far more forgiving than concrete, laminate, or hardwood.

Any furniture integrated into your basement blueprint will be much more difficult to move when placed on carpet. This is a big plus from a safety standpoint.

Compared to hardwood and other rigid flooring surfaces, carpet offers the most choices in terms of color, thickness, and texture. The ability to dye carpet provides an almost limitless number of choices, meaning you’ll have no problem finding the perfect carpet to match the rest of your basement’s aesthetics: paint color, furniture, etc.

The Cons of Carpeting

Floodwater damage is the biggest threat to basement carpeting. Even an inch of rain can necessitate removing the carpet, which when wet is a prime candidate for mold and mildew that can cause a number of health problems. Floodwater also carries with it harmful bacteria that is dangerous to anyone playing or walking on water-damaged carpet.

Of far less consequence but still well worth considering (especially with kids) is that spills and messes can be much harder to clean up on carpet than on hardwood or laminate. Especially stubborn spills might even require re-patching the carpet, which requires the damaged swath of carpet to be cut out and replaced with a clean piece.

Even in the absence of major spills, carpet must be cleaned more frequently than other surfaces. This is extra important if you have pets and/or family members with allergies.

If you’re lucky enough to avoid water damage or spills on your basement carpet, it will still possess a shorter lifespan than wood flooring and similar surfaces. Take this into account when developing your homeowner’s budget, because carpet can be expensive to replace.
