Description

KTtron-8 is an ultra-fast-setting dry cement mixture engineered by NPO KT (KT TRON Plant, Yekaterinburg) specifically for the emergency repair of actively leaking concrete structures. When blended with water it forms a non-shrink, thixotropic mortar that achieves initial set within just one minute and reaches a bond strength of 0.5 MPa within the first hour — making it one of the fastest-acting hydraulic plugging compounds available.

The cured material develops a compressive strength of at least 40 MPa, achieves a waterproof rating of W4 at 24 hours, and carries a frost resistance grade of F300, performing reliably across application temperatures from +5 °C to +35 °C and a wide pH range of 5 to 14. Uniquely, KTtron-8 is approved for contact with drinking water and contains no chlorides or solvents, eliminating any risk of reinforcement corrosion.

The material also resists highly aggressive chemical environments — including ammonium, magnesium, and sulfate solutions, alkaline media up to 8% NaOH, sea water, and petroleum products — making it well suited for civil, industrial, and hydraulic infrastructure repair. Packaged in handy 5 kg buckets with a 12-month shelf life, it requires no injection equipment: the mortar is simply mixed by hand to a clay-like consistency in seconds and pressed firmly into the prepared void.

Details & Equipment

Product & Application

KTtron-8 Packaging

KTtron-8 is supplied in 5 kg buckets stored at −30 °C to +50 °C with a 12-month guaranteed shelf life; the dry mixture requires only 0.21–0.22 L of water per kilogram to produce a workable, clay-like mortar ready for immediate application.

Leak Repair in Action

For a point leak the mortar is shaped into a cone and pressed firmly into the prepared void for 4–5 minutes; for openings exceeding 50 mm diameter the 'ring method' progressively reduces the hole until the remainder can be sealed with a single portion of KTtron-8.

Features

⚡

Ultra-Fast Setting

Initial set begins within 1 minute of mixing and bond strength to concrete reaches 0.5 MPa after just 1 hour, stopping active leaks almost instantly without any injection equipment.

💧

W4 Waterproof at 24 h

Achieves a minimum waterproof grade of W4 within 24 hours of application, providing reliable protection against water ingress from the very first day.

🏋️

High Strength & Adhesion

Cured material develops compressive strength of at least 40 MPa and adhesion of 1.5 MPa to concrete substrates, matching the structural performance of the surrounding concrete.

❄️

F300 Frost Resistance

Rated F300 for freeze-thaw durability and heat-stable up to 120 °C under constant exposure, ensuring long-term performance in demanding climates.

🧪

Broad Chemical Resistance

Stable across pH 5–14 and resistant to sulfate, magnesium, ammonium, alkaline (8% NaOH), sea water, and petroleum product environments.

🚰

Drinking-Water Safe

Certified for contact with potable water and chloride-free, protecting reinforcement from corrosion and meeting sanitary requirements for water-supply infrastructure.

Buyer Benefits

Stops active pressurised leaks in seconds — no injection equipment needed, just mix with water and press into the void by hand
Non-shrink formulation creates a tight, void-free plug that remains bonded over time without relaxation or cracking
Serves as a compatible first-stage repair within the full KTtron system, ready for overcoating with KTtron-1, KTtron-2, or KTtron-3 after just 1 hour
Chloride-free and solvent-free composition eliminates corrosion risk in reinforced concrete and is safe for workers
Approved for use in drinking-water reservoirs, water-treatment facilities, and potable-water pipelines
Operates across pH 5–14, making it viable in chemically aggressive industrial and municipal environments
Simple hand-mix application in a small container with no specialist tools or skilled operatives required

Applications

Emergency stopping of active pressurised water leaks through cracks and point defects in concrete walls and floors Sealing filtration through construction joints and cold joints in basements and below-grade structures Primary waterproofing treatment of joints in floors and walls before applying KTtron penetrating systems Plugging formwork tie-hole voids and anchor bolt pockets in concrete structures Grouting and anchoring bolts, anchors, pipes, and sanitary equipment into concrete Sealing cracks and joints in drinking-water reservoirs and water-treatment facilities Repair of leaking joints in industrial process tanks and channels handling aggressive liquids Stopping diffuse water filtration through porous or cracked concrete surfaces via the dry-rubbing technique
