Delivering stability and support<\/b><\/h4>


<\/p>

The primary lining<\/b> phase delivers the stability of the tunnel structure providing immediate support to the excavated ground. <\/p>

This temporary supporting lining is commonly made of steel fiber reinforced shotcrete. <\/p>

When required, this phase also features the installation of reinforcement elements consisting of steel arched sections that have the shape of the tunnel contour.<\/p><\/p><\/div><\/div><\/div>

Reducing costs and increasing productivity with the B.Zero TondoTM<\/h4>


<\/p>

Our patented B.Zero TondoTM Tunnel Support System<\/b> is a new solution in tunnelling and provides extremely efficient first-stage support. B.Zero.TondoTM is unique tubular steel-arch ribs, filled with pumped concrete in-situ and offering greater structural efficiency than traditional steel-arch supports. <\/p>


<\/p>

Therefore fewer B.Zero TondoTM arches are needed, reducing costs and increasing tunnel productivity.<\/p><\/p><\/div><\/div><\/div>
