Tunnelling

Sprayed concrete (shotcrete)Tunnel linings, slopes and shafts placed by spraying. 3 matches → Structural concreteFrames, slabs, columns and walls: workability, strength and durability. 14 matches → Ready-mix superplasticiser rangeThe KingMix polycarboxylate (PCE) range for ready-mix and site-batched concrete. Grades differ in water reduction, slump retention and early strength; your KingKrete engineer matches the grade to your cement, aggregates and placing time. 48 matches → Watertight concreteBasements, tanks and below-ground structures built watertight from the mix. 7 matches → Precast & early-strength concreteFast mould turnaround and early strength for precast elements. 17 matches → Hot-weather concretingFor: summer pours in high temperatures: slump retention and controlled setting. 13 matches → Self-compacting concreteFor: congested reinforcement and fair-faced elements placed without vibration. 3 matches → Corrosion-protected concreteFor: reinforced concrete exposed to chlorides from sea air, de-icing or car traffic. 2 matches → Piles & diaphragm wallsFor: bored piles and diaphragm walls: long workability and cohesive tremie concrete. 4 matches →

Curing of slabs & decksCuring compounds that protect fresh concrete as it gains strength. Remove the curing film before any bonded screed, coating or tiling. 11 matches → Formwork releaseRelease agents for clean striking of cast-in-place formwork. 5 matches → Evaporation control in hot weatherFor: fresh slabs in sun and wind: stops plastic-shrinkage cracking before curing starts. 3 matches →

Wet or moving crack injectionFor: active leaks, live/moving cracks. 2 matches → Active water leak pluggingFor: immediate stop to running water. 2 matches → Structural crack injectionFor: dry, static cracks 0.2-10mm. 2 matches → Structural repair, vertical or overheadFor: high strength, trowel-grade. 4 matches → Steel reinforcement primingFor: exposed or corroding rebar before patching. 4 matches → Structural strengthening (CFRP)Carbon-fibre plates and wraps to add capacity to beams, slabs and columns. 6 matches → Sprayed concrete repairFor: large areas of spalled soffits and walls, rebuilt by spraying. 7 matches →

Post-tensioned cable duct groutingFor: eN 447 compliance required. 1 match → Structural anchoringFor: cracked or uncracked concrete, seismic-rated. 2 matches → Bearings & base platesGrouting bridge bearings, column base plates and plinths. 28 matches →

Exterior movement jointsFor: weather-exposed, high movement. 9 matches → Pavement and runway jointsFor: fuel and oil exposure, trafficked. 9 matches → Fire-rated joints & penetrationsFor: joints and service penetrations in fire-rated walls and floors. 2 matches →

Facade anti-carbonationProtective coatings that stop carbonation of exposed concrete. 5 matches →

Platforms & UndercroftFloor systems for platforms & undercroft. 2 matches →

Tunnel LiningsWaterproofing for: cut-and-cover / accessible; high groundwater expected. 9 matches → Drainage Structures (Culverts, Channels)Waterproofing for: gravity flow; permanently wet; aggressive / contaminated water. 14 matches → Expansion & Movement Joints (Infrastructure)Waterproofing for: static construction joints; movement / seismic joints. 23 matches → Plant RoomsWaterproofing for: wet service areas; critical equipment areas. 6 matches →
