Concrete repair materials can be either from concrete itself or polymer based products by manufactures such as Hilti, Sika or Mapei as usually found in Malaysia. The use of polymer based products are normally used due to easier handling, higher strength and consistency in quality.
The specification for the materials used for concrete has been develop by CKAS and are being used in all of our concrete repair projects/jobs.
Currently, we have recently updated the following specification for JKR use, namely:
i) Specification for Concrete Patch Repair - JKR 20601-0254-19
ii) Specification for Concrete Crack Repair - JKR 20601-0250-18
Currently the following specifications are still in use but the updates to this specification is in progress and expected to be used by the first quarter of 2020.
iii) Specification for Protective Coatings
iv) Specifications for Repair to Spall & Damaged Concrete by Sprayed Concrete
v) Specification for Formwork Pressure Grouting
vi) Specification for Free Flow Formed Concrete
vii) Specification for Waterproofing
These seven specifications are to be used on repair or retrofitting projects and are available at Bahagian Kejuruteraan Forensik Struktur, CKAS located at Tingkat 4, Blok F.
Apart from this, we do produce a guideline on hardened concrete testing which will guide the user to specify the correct test.
