Product Range — Waterproofing
| Product | Best For |
|---|---|
| TREMproof 250GC (18.9L) | The flagship polyurethane membrane — approved for green (24-hour) and damp concrete, making it essential for fast-track construction. Rapid curing, low VOC, primer-less on most concrete. The go-to choice for below-grade and above-grade waterproofing when you cannot wait for concrete to fully cure. |
| Vulkem NEM PLUS (15L) | Single-component, single-coat polyurethane membrane for under-tile waterproofing. Australian-made with high tensile strength — a solvent-based option that provides a robust, durable membrane beneath tiled surfaces in bathrooms, balconies, and wet areas. |
| Vulkem H2 Plus (15L) | Water-based alternative to NEM PLUS — single-component, rapid-cure acrylic membrane with micro fibres for added strength. Lower odour and easier cleanup make it practical for occupied buildings and sensitive environments. Best for internal wet areas where a water-based system is preferred. |
| AlphaGuard Bio System (Base + Top Coat kits) | Premium two-coat polyurethane roofing restoration system with bio-based content. Odourless and high-performing — ideal for re-roofing commercial buildings where occupants are present. Available in grey and white top coats. Requires AlphaGuard WB Primer. |
| TREMproof 201/60R (18.9L) | Standard polyurethane membrane for below-grade and above-grade applications. Primer-less on most concrete — a proven, more cost-effective option than the 250GC when green concrete approval is not needed. |
| TREMproof 90 (30L kit) | Two-component acrylic membrane with fibrous reinforcement — a versatile option for general waterproofing. |
| TREMproof RT Plus (30kg kit) | Cementitious coating for negative-side waterproofing — designed for concrete tanks and below-grade structures where water pressure comes from outside. |
| Torch-On Membranes (3000, 4000M, Anti-Root) | APP-modified bituminous torch-applied membranes for podium decks, roofing, and planter boxes. The 4000M (4mm thick) offers superior performance. Anti-Root variant prevents root penetration. |
| Sheet Membranes (560A, Dualproof C) | Self-adhesive (560A) and PVC (Dualproof C) sheet membranes for below-grade and structural waterproofing. |
| Vandex Crystalline Range (BB 75, Plug, Cemline, OS 5) | Cementitious crystalline waterproofing that penetrates and seals concrete from within. Ideal for water tanks, basements, and remedial work. |
| Bituminous Products (Hydroseal, Pabkote) | Brush-on waterproofing for general damp-proofing. Pabkote 3 is the budget-friendly option for large areas. |
| Primers (TREMprime, Vulkem 171, 191QD, WB Primer, 200EC) | Full primer range matched to specific Tremco membrane systems — porous, non-porous, metal, and epoxy options. |
| Accessories | Perm A Fab reinforcing fabric, DualFlex flashing, drainage cells, TREMboard protection board, backing rods (open and closed cell), and solvents. |
| Construction Sealants (Dymonic 100, Dymonic FC, TREMflex 50, SG300, TREMglaze 50, TREMfil 101) | Polyurethane, silicone, and facade sealants for movement joints, structural glazing, and polycarbonate sealing. Dymonic FC offers fast cure for facade applications; SG300 is a structural glazing silicone. |
| Fire-Rated Sealants (TREMstop PU, TREMstop Acrylic FYREthane) | Fire-rated polyurethane and acrylic sealants for penetration and joint sealing in fire-rated construction. |
| Concrete Repair & Grouting (Euco range — QWIKjoint, QWIKstitch, Eucocrete, Veraspeed, TAMMSGrout, Tremgrout, Tremie Grout) | Complete concrete repair system including polyurea floor joint fillers, rapid-set repair mortars, structural repair mortars, fairing coats, high-strength epoxy grouts, non-shrink grouts, and underwater grout. |
| Curing Compounds (Evencure AA, AC, BCP, W30, X-Pose, XDS NXGEN, Evenrange) | Full range of concrete curing compounds and finishing aids in 20L, 200L, and 1000L sizes. Includes wax-based, acrylic, and lithium-based formulations. Evenrange includes form release and cure strippers. |
| Foam Seals (Presstite, Presstite FR, illmod 600, illbruck) | PU foam sealing strips for roofing profiles (Custom Orb, Trimdeck), flat foam strips in various widths, fire-rated FR variants, illmod 600 pre-compressed expanding foam seals for window and facade joints, and illbruck expanding PU foams. |
| Concrete Protection (Eucoweld, Zinc Rich Primer, Sentinel Galvanic Anodes) | Bonding agents, protective coatings for reinforcing steel, and galvanic anodes for cathodic protection of concrete structures. |
| Structural Adhesives (Dural HS Gel, Dural 452 MV) | High-strength epoxy adhesive systems for structural bonding and anchoring applications. |

Common Questions
Should I use Vulkem NEM PLUS or Vulkem H2 Plus? — NEM PLUS is a solvent-based polyurethane with high tensile strength — choose it when maximum durability under tiles is the priority. H2 Plus is water-based with lower odour and easier cleanup — choose it for occupied buildings or where water-based products are specified. Both are single-component, single-coat membranes.
What makes TREMproof 250GC different from 201/60R? — The 250GC is approved for green (24-hour) and damp concrete, essential for fast-track construction. The 201/60R is a proven standard membrane for cured concrete — more cost-effective when timing is not critical.
What is the AlphaGuard system? — A two-coat polyurethane roofing restoration system (base coat + top coat) with bio-based content. Odourless, making it ideal for re-roofing occupied commercial buildings. Requires AlphaGuard WB Primer.
Can Tremco products be used for potable water tanks? — TREMproof W95 is approved for potable water. For standard concrete tanks, TREMproof RT Plus and the Vandex crystalline range are suitable.
Does Tremco supply primers? — Yes — a full range matched to each membrane system. Always check the technical data sheet for the correct primer-membrane pairing.
