SpECbuild SG15

SpECbuild SG15 is designed for a variety of structural repair applications, providing reliable solutions in demanding conditions:

• Repairs to structural concrete elements, e.g. reinforced beams and columns
  
• Highly trafficked surfaces, particularly transition strips adjacent to mechanical bridge joints
  
• Repairs in marine environments or other situations where concrete is in contact with chloride or sulphate solutions
  

SpECbuild SG15 offers a range of advantages that make it an ideal choice for structural repair applications, ensuring long-lasting performance and reliability:

• High bond strength to concrete substances.
  
• Good abrasion resistance.
  
• High compressive strength.
  
• Coefficient of thermal expansion similar to host concrete.
  
• Compensated for plastic and long-term shrinkage.
  
• Low permeability providing protection against the ingress of chlorides and carbon dioxide.

The following section outlines the application process for SpECbuild SG15, providing essential steps for ensuring optimal performance:

It is essential that adequate preparation is carried out prior to the application of SpECbuild SG15. This preparation should ensure the removal of all grease, oil, and loose material. The area to be reinstated using SpECbuild SG15 should be cut back to a depth of at least 10mm to avoid “feather edging”. It is advisable to neatly delineate the repair boundary by saw cutting to a depth of 10mm.

For most situations, the substrate should be primed with SpECbuild Primer S1. Initially, the surface should be thoroughly saturated without standing water prior to the primer being applied by brush, ensuring intimate contact with the substrate. This is best achieved by using a circular scrubbing action. SpECbuild SG15 can be applied as soon as the primer becomes tacky.

For mixing a single bag, place 2.25 to 2.75 litres of clean water in the mixing vessel and slowly add the contents of the bag with the mixer running. The product should be mixed for a minimum of 5 minutes. This product cannot be mixed by hand.

SpECbuild SG15 can be applied by a gloved hand to ensure thorough compaction around the reinforcement and against the edges of the reinstatement area. The repair is then trowel finished. The product can be applied up to 15mm in thickness in vertical, unsupported situations.

SpECbuild SG15 should be cured using SpECcure WE. In extreme drying conditions, a second coat should be applied immediately after the first coat has dried.

SpECbuild SG15 is available in convenient packaging to ensure easy handling and application:

Product Packaging: 25kg bags

Coverage: 1.1m² @ 10mm thick
