A basement refers to one (shallow) or several (deep) floors of a building that are either partially or completely below the ground floor. Basement waterproofing is the practice of forming an impervious barrier around a basement. This barrier is designed to prevent any water from entering or escaping from the different sections of building structures.
The construction procedures and designs that are needed for the completion of basement waterproofing are actually more crucial than the waterproofing itself. Basements are increasingly becoming more and more important for buildings as the availability and cost of real estate increases especially in urban areas. They provide much needed room for parking, commercial activities, entertainment activities or storage purposes. Technically, the term waterproofing encompasses protection from all kinds of liquids or gases and not just water.
Most basements are constructed from concrete and as such, basement waterproofing mainly involves its reinforcement. Several factors are taken into consideration including internal facings, section changes, permissible cracks and point loads. Basically basement waterproofing involves the control of cracking, prevention of differential settlement and installation of a dense structure that is impervious to water.
Importance Of Basement Waterproofing
There are several environmental factors that make this practice very important. The gases and liquids that are present in underlying and surrounding soil may penetrate low-grade concrete and seep into a building. In developed areas, ground water and soil maybe easily contaminated by hazardous liquids or gases. These may include methane from decomposed organic matter and leaks from septic and sewer systems.
Ground water may be able to move upward or laterally. The water that seeps through walls of the basement can stagnate on the floor or even cause flooding in the event of heavy downpour. Additionally, water penetrates into basement through vapor. Once this moisture condenses on the internal surfaces, it can cause proliferation of undesirable organisms such as molds, bacteria, spores and fungi.
Waterproofing Foundation Products Ohio
The selection of waterproofing material is a very important step in the procedure. Several factors have to be considered including presence of aggressive chemicals, service life of the system, internal dryness, cost efficiency, expertise available and hydrostatic pressure resistance.
There are three main categories of waterproofing foundation products Ohio; membrane forming materials, lining forming materials, preformed materials and cementitious materials.
1. Membrane Forming Materials
There are two main types of membrane forming waterproofing materials; polymer based and tar/bitumen based materials. Polymer based materials are asphaltic bitumen placed under tar-based coatings. Tar based materials include cold-applied asphalt or coal tar. They are effective for damp production but are relatively unstable.
2. Preformed Membranes
These materials mask surfaces with in-situ membranes bearing bonding adhesives. They are factory made, quality controlled and recommendable for larger or deep basements. They require skilled human resource for installation and include bitumen felts, Butyl rubber sheets, PVC sheets, Hypalon and Polyethylene.
3. Cementitious Materials
These materials result in a superior bond with substrates but lack the ability to bridge cracks. They provide excellence waterproofing when they are modified with a polymer. They possess high elasticity and bond well to concrete surfaces. Cementitious materials include integral crystalline that form crystals when they come into contact with water and thus seal minute pores.
Roof Waterproofing Ohio
Roof waterproofing is particularly recommended for reinforced concrete roofs that are known to exhibit capillary tracts and pores. Concrete is often weak in tension and cracks may form due to thermal expansion and contraction.
Roof waterproofing is therefore important since they are constantly exposed to the elements. There are two main types of roof waterproofing.
1. Liquid Roof Waterproofing
Liquid proofing involves the application of a specially designed liquid roof coating. The coating is monolithic and fully bonded. Once it cures, it forms an elastomeric waterproof membrane on the roof that resembles rubber.
It is capable of expanding and contracting without damage. They include bitumen-based, polymer based and heated coal tar-based membranes.
2. Pre-Formed Sheet Membranes
These roof waterproofing membranes are attached with an adhesive or through the application of heat. The most commonly employed preformed membranes on roof include polymer-modified bitumen and PVC membranes.
The former are bonded to fiberglass or polyester and produced into rolls. They can easily elongate and recover making them ideal for stress protection against temperature changes, winds as well as roof expansion and contraction.
