The reinforcement layer that embeds between the coats of your waterproofing membrane — adding mechanical strength and crack-bridging performance for terraces, pools, bathrooms and water tanks.
Everything you need to know about this reinforcement fabric.
Mapei Mapetex Sel N is a non-woven polypropylene fabric engineered to reinforce cementitious waterproofing membranes, giving them extra mechanical strength and crack-bridging performance where movement and stress concentrate. Made from continuous synthetic polypropylene fibres bonded by a mechanical needle-punch process, the fabric is embedded between the coats of a flexible waterproofing product so the finished membrane resists cracking, tearing and micro-fractures over its whole life.
Available at Shabbiri Hardware, Ongata Rongai, in a convenient 25 m × 1 m roll — ready to cut for corners, joints and full-surface reinforcement.
Why professionals choose Mapetex Sel N.
Reinforces waterproofing membranes so cracks and micro-fractures don't spread through the finish.
High tensile strength and flexibility for movement-prone areas that flex without splitting.
Resistant to alkalis and atmospheric agents for dependable long-term performance.
Will not shrink or distort, so the reinforcement stays exactly where you laid it.
Designed to work with Mapelastic Turbo and Mapelastic Smart membranes.
Perfect for terraces, balconies, bathrooms, pools and water tanks before tiling.

Ideal reinforcement across these waterproofing applications.
Embedding the fabric correctly is what makes the reinforcement work.
Ensure it is sound, clean and free of dust, grease and loose material. Cementitious surfaces should be damp with no standing water. Repair cracks first.
Spread a uniform 1–2 mm layer of your flexible waterproofing product (e.g. Mapelastic Turbo / Smart) with a trowel.
While the first coat is fresh, lay Mapetex Sel N into it and press until fully embedded, with no air pockets. Overlap adjacent strips by at least 5 cm at all joints.
Once the first layer is walkable, apply a second 1–2 mm coat, fully covering the fabric.
Allow the membrane to cure per the product data sheet before tiling or filling a pool.
Keep the fabric fully sandwiched between the two coats and never leave it exposed — complete coverage is what delivers maximum strength.
Quick answers to what customers ask most.
It's a non-woven polypropylene fabric embedded between the coats of a flexible waterproofing membrane to reinforce it, bridge cracks and add extra mechanical strength where movement and stress concentrate.
It's the recommended reinforcement layer for Mapei's flexible cementitious systems such as Mapelastic Turbo and Mapelastic Smart.
Mapetex Sel N is supplied in a 25 m long by 1 m wide roll, ready to cut for corners, joints and full-surface reinforcement.
It's ideal for waterproofing balconies, terraces, bathrooms, swimming pools and water tanks before tiling.
