A globally acclaimed structural strengthening system from Sika was specified for the refurbishment of South Africa’s third-busiest railway station, Mabopane Station in Pretoria, in an area identified as a high-density activity node.
Pretoria’s Mabopane Station, the third-busiest railway station in the country, underwent refurbishment in 2016 as part of the Passenger Rail Agency of South Africa (PRASA) National Station Upgrade Programme.
MMA Posten Engineers SA wasted no time in specifying Sika’s structural strengthening system, which was applied by specialist construction company, Freyssinet. Sika’s Peter van Eden was the technical sales consultant advising onsite.
Sika CarboDur S1012 plates
Manufactured from carbon fibre reinforced polymer (CFRP), Sika CarboDur plates were bonded onto the station walls as external reinforcement. Although these non-corrosive, pultruded laminates are extremely strong and durable, they are supplied in lightweight rolls for easy transportation and installation.
Some 800 kits of Sikadur-30, a structural, two-part adhesive, were used to bond a total of 10 420m of Sika CarboDur S1012 plates. Easy to mix and apply, it provides excellent adhesion, hardens without shrinkage and is impervious to liquids and water vapour.
SikaWrap-300 C and SikaWrap-600 C
Manufactured from unidirectional, woven, carbon fibre fabric, SikaWrap-300 C (800m) and SikaWrap-600 C (1 200m) were applied to the station walls to increase flexural and loading capacity. Both products are low density for minimal additional weight.
Sikadur-330 (869 kits), a two-part, epoxy-based impregnation adhesive, was used as a bonding agent for the SikaWrap products. Easy to mix and apply, it provides good adhesion to many substrates and requires no separate primer.
Constant dust from construction and earthworks in the vicinity, as well as moving scaffolding around the busy station, were big challenges for the contractor, but now, being structurally strengthened by state-of-the-art products, Mabopane Station will be able to accommodate the high-density activity of this important urban core.
