Tips & Advice
What is a cementitious waterproofing system?
Cementitious waterproofing systems that uses a mix of chemicals, applied t to the surface of cement with ing brushes or sprayers; once dried, it forms a protective membrane across the surface of the cement. This method is relatively user-friendly for DIYers. One downside is it does not naturally adjust to any changes in the cement (like cracks). There are additives you can use to increase the malleability in cementitious waterproofing chemicals to account for slight changes in the cement.
What is bituminous damp proofing?
Bituminous damp proofing is not just a cool-sounding term, it’s a great way to waterproof materials. Damp proofing materials are chemical compounds that, when applied to the surface of a variety of materials like wood, metal and concrete, provide a breathable membrane that allows internal moisture to escape, while providing a protective water-resistant surface. It can be painted or sprayed on and is popular on outdoor decks and fencing materials.
What is waterproof concrete?
Waterproof concrete has been treated to prevent interior or exterior water or moisture buildup. Crystalline waterproofing is a process used in the concrete mixing to eliminate the naturally porous elements inside of concrete. Chemicals can also be applied to the exterior of any concrete structure to provide a surface membrane that shields the concrete from any external water sources. Both can be used to create a virtually waterproof concrete.
What is crystalline waterproofing?
Crystalline waterproofing is an admixture that is used to create permanently waterproof concrete. Concrete is a naturally porous material with tiny grooves and capillaries inside. Crystalline waterproofing makes concrete non-porous and uses chemicals that change the actual chemical makeup of the concrete, allowing those grooves to be filled in and, making it waterproof from the inside out.
What is elastomeric waterproofing?
Elastomeric waterproofing is a polymer with viscoelasticity, meaning it has both viscosity and elasticity properties, which makes it kind of thick and gooey.Elastomeric waterproofing materials are ideal for concrete structures as they provide a strong exterior coat that is malleable prior to drying, so it can fill nooks and crannies to provide maximum coverage and protection. Its chemical makeup also makes it durable, mold and mildew resistant, and, of course, highly water resistant. Elastomeric waterproofing is an exterior-based type of waterproofing that goes between the structure (your house, building, or fence) and the elements.
What chemicals are used in waterproofing?
Most chemicals used in waterproofing are acrylic, elastomeric acrylic, and latex based. Some chemicals are designed for internal usage, such as elasomeric waterproofing, which is designed to be mixed into concrete to create waterproofing from the inside out. Other materials are designed to create a surface membrane, or a protective layer or barrier between the structure and the outside elements.
What is the purpose of waterproofing?
Waterproofing is a chemical process used to prevent water or moisture from seeping into structures, especially buildings and housing structures where they can cause damage. Waterproofing can be done to metals, woods and concrete; homes, buildings, fences, decks, driveways, roofs and basements are all typical structures that need to be waterproofed.
What are the different types of foundation repair methods?
There are several methods of foundation repair, based on the problem.
- Sealants and masonry patches can be used for minor foundation cracks and imperfections.
- Slab jacking is a process used for sunken foundations that raises the sinking foundation back to normal by pumping a fill material below the foundation to regain its original position. This method, as laborious as it sounds, can actually be done quickly and efficiently.
- The most severe form of foundation repair is piering, or piling, in which steel or cement piers or pilings are driven through the foundation into the ground to correct and re-stabilize the foundation. In steel-pressed piling technique, steel rods or beams are driven into the ground via a hydraulic ram to the foundation back to its normal position. In concrete-pressed piling, holes are drilled deep and filled with reinforcement materials. This is a cheaper solution, but only a short-term one.
How can foundation problems be prevented?
There are a few ways that can help decrease chances for foundation problems, and they are all water-related.
- Install quality gutters around your roof with downspouts that take the water at least 3-5 feet away from the foundation. This can prevent water from pooling around your foundation.
- Address the soil grade in your yard. Your soil type and the slope of the land are major factors in water retention and pooling. Be aware of trees and plants that affect moisture levels in the soil adjacent to the foundation. In drought conditions, consider a soaker hose around the perimeter to prevent the soil, particularly clay soil, from drying, shrinking and cracking.
- Check all plumbing and drainage properties regularly for leaks. Consider a French drain, which is an underground trench system where excess water is collected and removed.
How can you tell if a foundation has problems?
There are several signs you may have foundation problems. If your foundation is visible (you have a basement or crawlspace foundation) there will be visible evidence of cracking or crumbling. If your walls are warped, or the floor slopes, those are major indicators you foundation is sinking. If doors are hard to open or close, or get stuck, this may be a foundation problem (but could also just be a door frame issue, so don’t freak out yet). Cracks on the walls or on floor tiles are a sign. Water in the basement or crawlspace can be a definite danger sign. Warped walls or gaps between the walls and ceiling should be cause for concern. Having any of these symptoms (outside of the blatant visual evidence of a cracked or crumbling foundation) might be a warning sign, but is not necessarily proof of foundation problems. However, if you do have symptoms, you would be wise to have an inspection done. Problems like that only get worse.
