Product Description

Base‑less Self‑adhesive Modified Bitumen Waterproof Membrane

 

Product Introduction

Baseless self‑adhesive modified bitumen waterproof membrane is a sheet‑type waterproof material without substrate. It is mainly composed of modified bitumen self‑adhesive compound, covered with separating films on both top and bottom sides. It can be installed by the wet‑lay construction method. Full adhesion between the membrane and substrate is achieved by cement paste. It is suitable for construction on damp base surfaces. No open‑flame hot‑melting is required for cold installation. Featuring dual functions of waterproofing and moisture‑proofing, it is widely applied in various building waterproofing projects.

Product Features

  • Baseless structure with high elongation and good flexibility, capable of adapting to substrate deformation and offering strong crack‑resistance.
  • Supports cold wet‑lay construction without open‑flame heating. Safe and eco‑friendly, ideal for construction sites where open fire is prohibited.
  • Installable on damp substrates. Full bonding with cement paste effectively prevents water channeling under the waterproof layer.
  • Self‑adhesive overlapping joints ensure reliable sealing. Simple installation shortens project construction periods.
  • Excellent high‑low temperature resistance with long‑lasting stable adhesion, delivering both waterproof and moisture‑proof performance.
  • Great adaptability to substrates, performing well for special‑shaped areas such as internal/external corners and pipe roots.

 

Scope of Application

  • Underground waterproofing and moisture‑proofing projects including basement slabs and side walls of civil and industrial buildings.
  • Non‑exposed roof waterproofing, renovation and leak‑repair works for old roofs.
  • Municipal and hydraulic waterproof projects such as tunnels, cut‑and‑cover subways, water pools and water channels.
  • Waterproof construction scenarios where open fire is strictly forbidden, such as oil depots and workshops.
  • Moisture‑proof and waterproof areas including kitchens, bathrooms and underground parking garages.
