WP CONCENTRATE

Waterproofing by Crystallisation

Overview

Galaxie WP Concentrate is a surface-applied crystalline waterproofing treatment for concrete. Supplied as a dry powder consisting of Portland cement, specially treated quartz sand and a proprietary blend of active chemicals, it is mixed with water on site and applied directly to prepared concrete surfaces. No primer or separate bonding agent is required.Once applied, the active chemicals react with free lime and moisture in the concrete capillary system to form insoluble crystalline complexes. These crystals progressively block capillaries and minor shrinkage cracks, preventing water ingress even under sustained hydrostatic pressure. The treatment remains breathable water vapour can still pass through the structure. Crystal growth continues as long as moisture and free lime are present, giving Galaxie WP Concentrate ongoing self-sealing capability throughout the life of the concrete.In addition to waterproofing, WP Concentrate protects concrete against seawater, wastewater, aggressive groundwater and certain chemical solutions. It is potable water approved and is suitable for water storage tanks and reservoirs.

WP PREMIX

Waterproofing by Crystallisation

Overview

WP Premix is a single-component crystalline waterproofing slurry for concrete. Supplied as a dry powder requiring only the addition of clean water on site, it can be used as a standalone damp-proofing treatment or as a second coat over Galaxie WP Concentrate where a two-coat system is specified. Applied as a second coat, WP Premix chemically reinforces the crystalline layer and produces a harder surface finish.WP Premix prevents water and liquid penetration from any direction by triggering a catalytic reaction with free lime and moisture in the concrete capillary system, forming insoluble crystalline complexes that permanently block capillaries and pores. The treatment becomes an integral part of the substrate and cannot puncture, tear or delaminate.

WP SDW 1

Silicate Densifier and Water proofer

Overview

Galaxie SDW 1 is a chemically modified silicate densifier and waterproofing solution designed to penetrate concrete substrates. It reacts with free lime (calcium hydroxide) and moisture to form an insoluble calcium silicate hydrate (CSH) gel within pores, capillaries, and micro-cracks, permanently densifying the concrete matrix. By densifying the concrete, the gel creates a sub-surface barrier against the ingress of water and contaminants such as chloride ions.

Benefits

•Water-based, non-toxic, VOC-free
•Long-term performance with no requirement for reapplication under normal service conditions
•Fully trafficable once cured
•Allows easy identification and remediation of persistent leaks or cracks without the need to remove membranes
•Capable of sealing non-moving shrinkage cracks up to 2.0 mm, subject to substrate condition

WP SDW 7

Crystalline Silicate Waterproofer & Hardener

Overview

WP SDW 7 is a chemically modified silicate densifier and waterproofing solution designed to penetrate deep into concrete substrates. Its biowetting formulation lowers surface tension so the product wets out fast and penetrates further than standard silicate sealers, migrating through the concrete's capillary network to reach fine pores that untreated products cannot.It reacts with free lime (calcium hydroxide) and moisture in the concrete to form an insoluble calcium silicate gel within the pores, capillaries and micro-cracks. This gel permanently densifies the concrete matrix, blocks the pathways used by water and waterborne salts, and seals static cracks up to 2.0 mm wide. Because the reaction happens below the surface rather than forming a film, the concrete keeps its natural texture and stays fully trafficable, there's no risk of the bubbling, peeling or blistering you get with film-forming coatings.The gel stays active for the life of the structure. If a hairline crack opens up later, moisture reaching it triggers the same reaction and reseals it no reapplication needed.

Benefits

•Biowetting formulation for fast, even wetting and deeper penetration.
•Water-based, non-toxic, low-odour.
•Seals static concrete cracks up to 2.0 mm wide.
•Self-healing reseals future hairline cracks on contact with moisture, no reapplication needed.
•Reduces chloride diffusion coefficient by up to 89%, protecting reinforcing steel.
•Reduces water permeability by up to 70%.
•Fully trafficable immediately after the first water-cure cycle no site downtime.
•No film to bubble, peel or blister concrete keeps its natural surface texture and grip.
•Resists heavy mechanical wear, abrasion and vehicle traffic.

General Application

•Infrastructure & asset protection: multi-level car parks, road and rail bridge decks, airport runways, taxiways and aprons.
•Civil & marine structures: wharf decks, concrete piers, splash-zone infrastructure, marine retaining walls.
•Commercial building envelopes: exposed concrete rooftops, podium decks, facades, pre-cast panels.
•Water management: water-retaining structures, containment tanks, storm channels, reservoirs.
•Internal wet areas: under-tile waterproofing for commercial shower recesses and non-glazed tiled zones.

SBR 46

Polymer Latex Additive

Overview

Reinjekt 2 is a pre-installed multiple-injection hose system that eliminates the need for concrete drilling at construction joints. Designed for contractors who need a reliable, cost-effective waterproofing solution that can be installed quickly during construction and re-injected on demand if leakage occurs.Installed as a joint packing before concrete is poured, the system covers the entire construction joint through a dedicated hose — no drilling required later. This means injection access is guaranteed from day one, saving time and cost if remedial waterproofing is ever needed.Reinjekt 2 is constructed from specially formulated plastic with special slots that prevent the infiltration of concrete water and laitance during casting, but open when internal pressure is applied. Its flexible nature allows it to follow contours and it should be placed in 10 metre lengths, or up to 30 metres if required.

Benefits

•Economical: simple parts and accessories reduce labour and material costs
•Fast installation: clips and pre-cut lengths mean minimal site disruption and no specialist equipment needed
•Can be injected with all currently available grouting materials, including PU resin, EP resin, AC resin and ultra-fine cement
•Repeated injection possible when using acrylic resins only — re-access the joint any time in the future without breaking out concrete
•Can withstand 12 metre head of concrete

General Application

•Construction joints in impermeable concrete structures
•Interface joints of concrete slabs and shotcrete sprays
