Silta Ettan OY

Silta Ettan OY is a Finnish waterproofing contractor that regularly uses Mapei solutions to guarantee effective, high performance and long-lasting results.

Silta Ettan OY is a Finnish company specialised in the application of waterproofing systems favouring the use of polyurea-based membranes. The company invests heavily into the quality and durability of its operational activities and uses EN 1504-10:2017 as a reference standard. The company regularly uses Mapei solutions to guarantee effective, high performance and long-lasting results. Since 2021 it completed waterproofing work on 45,000 m² of decks using Mapei solutions.

For what type of application do you most frequently use polyurea-based products?

We use polyurea-based products first and foremost for waterproofing bridge decks with asphalt or concrete substrates.

In your opinion, what advantages do polyurea membranes by Mapei offer?

We appreciate the high and constant quality of products that lead to fewer problems arising on site. In addition, the elasticity of Mapei materials is higher than that of products from its competitors, and we also really appreciate the primers on offer which are able to completely seal pores.

PURTOP SYSTEM DECK waterproofing system was also applied on the decks of the Näkinsilta bridge.

What are the strong points of your collaboration with Mapei?

Firstly, I would say reliability. We always receive Mapei products when we need them, so we don’t have to deal with problems of availability. Also, Mapei is really flexible when it comes to processing and managing orders and this flexibility proved to be invaluable, even during the periods affected by the Coronavirus pandemic.

What projects have you recently completed with the contribution of Mapei products?

Amongst the most recent I would like to mention the Veturitien Bridge in the Pasila district of Helsinki, several bridges for the Crown Bridges project in Helsinki, and the first integrated tram and bus terminal in the Ruskeasuo district of Helsinki.
