In hydraulic engineering projects, waterproofing and seepage prevention are of paramount importance. Traditional sheet piles typically rely on gaskets to achieve waterproofing, which not only involves cumbersome construction but also frequently leads to issues such as gasket aging, detachment, and corrosion. This results in high maintenance costs and poses potential safety hazards. Our gasket-free plastic-steel sheet piles completely resolve this challenge; thanks to their precision structural design, they deliver maximum waterproofing performance without the need for gaskets.We employ a C-T type deep interlocking joint design. Through high-precision molds that precisely control joint dimensions, the male and female joints of each sheet pile interlock perfectly, ensuring sufficient interlocking depth and high contact integrity. During installation, simply drive the sheet piles into place one by one. Under the pressure of water and soil, the interlocking joints will tighten further, naturally forming a continuous, watertight barrier. This effectively prevents water penetration without the need for additional sealant or waterstop strips.

We use high-strength polymer composite materials to create the sheet pile body through one-piece molding. It is resistant to acids and alkalis, corrosion, and aging, and is suitable for various complex aquatic environments such as seawater, sewage, and acidic or alkaline soils. With a service life of over 50 years, it will not experience issues such as joint deformation or leakage even after long-term use. Additionally, by eliminating the need for sealing strips, the construction process is significantly simplified, improving efficiency while reducing labor and material costs, thereby lowering overall project expenses. Whether for riverbank protection, embankment reinforcement, or temporary cofferdams, these seal-strip-free plastic-steel sheet piles consistently deliver reliable waterproofing performance. They truly achieve maximum waterproofing effectiveness without the need for sealing strips, establishing a robust anti-seepage defense line for water conservancy projects.
