Top Factors that Determine the Type of Waterproofing Membrane to Use
There is nothing that screams, "Run!" louder than a restaurant kitchen that experiences groundwater leaks frequently. When diners go to a restaurant, they are looking for quality service from the food to the restaurant's décor. Notably, a commercial kitchen that allows groundwater to leak into it poses a health danger to guests. Therefore, it is critical to use a waterproofing membrane to shield your establishment from letting water in. Unfortunately, most restaurateurs believe that any waterproofing membrane will perform the intended function. However, nothing could be further from the truth because several factors guide the type of waterproofing membrane to use. Read on for useful ideas so that you do not make an expensive mistake.
Nature of the Soil -- Soil properties vary from one area to another; therefore, different waterproofing membranes will function differently. For instance, there are areas where the soil is highly alkaline or acidic. The waterproofing membrane you choose for such a site should withstand the adverse effects of acidic and alkaline soils on the material. Moreover, some soils are less permeable such as clay soil, and will, therefore, retain water for a long time. The best waterproofing membrane for such a site must be tightly knit to sustain hydrostatic pressure resulting from the low soil permeability. Most importantly, ensure that your contractor tests the soil before deciding on the right type of waterproofing membrane for your establishment.
Water Table -- How far is the foundation's ground slab from the water table? Your contractor must answer the critical question before they buy an appropriate waterproofing membrane. Moreover, the water table level determines whether you are required by law to apply waterproofing to your foundation. According to the International Building Code, a waterproofing membrane should be applied on below-grade buildings where the ground slab is less than 6 inches from the groundwater table. That does not mean you should ignore the waterproofing membrane if your foundation is far from the highest water table. It provides an excellent guide on whether to apply a waterproofing membrane or postpone it for a later time.
Building Occupancy -- A building's occupancy also determines what type of waterproofing membrane you apply. For example, a one-room structure cannot hold too many people. Therefore, the waterproofing membrane should not necessarily be the high-end type because there is little risk of stress weight on the waterproofing membrane. However, a building such as a restaurant, where occupancy can reach several hundred people at any given time, needs a robust waterproofing membrane. It will sustain the stress placed between the ground slab and the foundation for durable waterproofing.
