Sika floors Investec with seamless solutions
from Workplace
Sika’s high performance products
were specified for the completion of Investec S&B’s office building in Germiston, Johannesburg. The project was contracted to TEQC (Technology Equipment Quality Consultants) with the scope of works including moderate to severe concrete repair and refurbishment.
The entire 40 000m² floor area outside of the office block was repaired using Sikacrete-214 (450 kits), a free-flowing, high strength micro concrete with a maximum aggregate size of 9 mm. It is typically used for casting sections or members where the volumes required are too large for conventional grouts or too small and inaccessible for normal concreting procedures. Economical, easy to mix, apply and finish, Sikacrete-214 provides excellent adhesion and rapid strength development.
SikaTop Armatec-110 EpoCem was used prior to the application of Sikacrete-214 as a reinforcement corrosion protection for all the severely corroded steel and concrete surfaces in the warehouse. This
internationally approved cementitious, epoxy resin compensated three-component coating material provides several advantages including extended open times for repair mortars, excellent adhesion to concrete and steel, good resistance to water and chloride penetration, and high shear strength.
The mortar used for all concrete joint repairs to the warehouse floor and the entrance in the forklift traffic area was Sikadur-43 ZA (18 500 linear metres). This solvent-free, three-component, repair and filling mortar is based on a combination of epoxy resins and selected high strength aggregates. Sikadur-43 ZA provides rapid, shrinkage-free hardening and high mechanical strength as well as abrasion and impact resistance. Curing of Sikadur-43 ZA is unaffected by high humidity and therefore suitable for South Africa and the coastal regions. It is also easy to mix, apply and finish.
Sikaflex Construction is a polyurethane sealant and was used as a general purpose sealant for sealing joints. It is a one part, moisture curing, elastic joint sealant based on polyurethane.
