The middle-buried waterstop is a critical product used to install waterstops within concrete in settlement joints, deformation joints, etc., and it is capable of accommodating the horizontal expansion and contraction of concrete through the elasticity of rubber materials and its structural form. Utilizing the high elasticity and shrinkage change of rubber, it undergoes elastic deformation under various loads, thus effectively sealing and preventing water leakage and water intrusion in the building structure, while also providing shock absorption and adjustment, ensuring the service life of the project's buildings. There are certain conditions during its application. Let's take a look together below.
Inaccurate placement of the material can lead to severe issues, often causing the water-stopping strip to fold over to the edge of the seam, rendering it ineffective. Traditionally,钢丝 were used to stabilize the water-stopping strip, but under the pressure of grouting, they would deform or even break, resulting in poor performance. It is now recommended to use specialized steel sleeves or flat iron for stabilization.
The concrete below the waterstop on the top and bottom plates is not easily compacted with grout, and air is also not easily released. Moreover, the shrinkage formed during concrete curing often creates gaps between the waterstop and the underlying concrete, leading to leakage in the settlement joints. In light of such conditions, the clause requires the waterstops on the top and bottom plates to be installed in a bowl shape, which is beneficial for resolving the aforementioned issues.
The assembly of the embedded waterstop presents a challenge during the initial concrete pouring phase. At this point, the end mold is divided into two sections by the waterstop, which makes stabilizing the formwork difficult. Due to the unstable support of the end mold, not only does it lead to concrete leakage, but it also prevents proper grouting as per specifications. This results in poor compaction of the concrete at the settlement joint, leading to water seepage.
The seams of the waterstop are its own weak point for preventing seepage, thus, the fewer seams, the better. Due to varying project sizes, the lengths of the seams differ, and there is no strict limitation on the number of seams.
The waterstop at the corner cannot be folded into a 90-degree angle; the terms require it to be shaped into an arc for easy installation. Our company has been manufacturing various sizes of embedded waterstops and external backing waterstops for years, offering a rich range of dimensions and quality that fully meets industry standards. Should you have special requirements, we can customize and manufacture according to your needs. We guarantee quality and quantity, with safe and fast logistics shipping.
