Crystalline waterproofing and polyurethane injection are two popular methods for stopping leaks in underground structures like tunnels and mines. While both methods haveheir individual benefits, using them together can provide even greater protection for the structure.
Crystalline waterproofing is a type of chemical waterproofing that works by reacting with water and minerals in the concrete to form a crystalline structure that fills any cracks or voids in the concrete. This helps to create an impermeable barrier that stops water from seeping through the concrete. Crystalline waterproofing is a great option for stopping leaks because it is long-lasting, and it does not rely on surface applications like coatings, which can be damaged over time.
Polyurethane injection is another method for stopping leaks in underground structures. This method involves injecting a two-part polyurethane mixture into cracks and voids in the concrete. The mixture then expands to fill any gaps, creating a flexible, water-tight seal. Polyurethane injection is a quick and effective way to stop leaks, but it is not as long-lasting as crystalline waterproofing.
When used together, crystalline waterproofing and polyurethane injection can provide a comprehensive solution for stopping leaks in underground structures. The crystalline waterproofing provides a long-lasting, impermeable barrier, while the polyurethane injection stops any immediate leaks. This combination of methods can provide building owners with peace of mind, knowing that their structure is protected against water damage and potential collapse.
Using crystalline waterproofing in conjunction with polyurethane injection is an effective method for stopping leaks in underground structures. By combining the long-lasting protection of crystalline waterproofing with the quick and effective sealing of polyurethane injection, building owners can ensure that their structure is protected against water damage for many years to come.
