Corrosion Protection System | ENCAP6

Supplier: Mainmark

The ENCAP6 Corrosion Protection System is a Technologically Advanced Solution for Revitalising Ageing Infrastructure.


Mainmark specialises in the design, manufacture and installation of the ENCAP6™ corrosion protection systems for concrete and steel infrastructure, such as bridges, lift stations, pipe and tank relining and manholes. ENCAP6™ seals, protects and structurally reinforces ageing assets.

ENCAP6™ stops decay in six essential ways:

  1. Chemical Resistance
  2. Superior Adhesion
  3. Inflow and Infiltration
  4. Structural Enhancement
  5. Abrasion Resistance
  6. Permanent Solution

Chemical Resistance

Vinyl ester resins provide superior resistance to an extremely wide range of chemicals. The patented vinyl ester formulation provides better hydrolytic stability and is more chemically resistant than epoxies, polyureas and polyester resins.

Superior Adhesion

ENCAP6™ primers are specifically designed to chemically bond to both steel and concrete surfaces. Their adhesion capabilities are exceptional when compared to any other polymer lining technologies. Chemical bonding (and in the case of concrete, also effective mechanical bonding) is essential for long term protection as the bond eliminates the micro-spaces where corrosion starts to occur.

Inflow and Infiltration

ENCAP6™ is able to permeate, fill and stabilise small cracks, gaps and seams in a single application. Larger gaps are repaired with compatible fillers that effectively bond to the new ENCAP6™ liner to meet or exceed EPA requirements.

Structural Enhancement

The patented formulation of ENCAP6™ is based on a microfibre infused vinyl ester resin that has remarkable structural properties and can be applied to any requisite thickness, depending on the structural performance that is required. It can be either used as an anti-corrosion spray or applied with layers of glass fabric to deliver specified, engineered outcomes.

Abrasion Resistance

ENCAP6™ corrosion protection offers a hard-wearing surface that has substantial abrasion and impact resistance. Ultra-hard-wearing specialist formulations are also available on request to meet site-specific needs.

Permanent Solution

ENCAP6™ has a high degree of hydrolytic stability compared to other polymer solutions, which guarantees a longer service life when in contact with moisture, water or chemicals.

Using ENCAP6™ corrosion protection, Mainmark works to reduce capital replacement costs and deliver significant labour and capital savings for typical applications such as:

  • Bridges – steel and concrete coating solutions
  • Sewage lift stations – repair, rehabilitate, coat and line wastewater and water infrastructure
  • Pipe and tank relining – more cost effective to rehabilitate than to excavate and replace
  • Manholes – our chemical resistant coatings protect against deterioration
