Renovation fire damaged church Galmaarden Belgium

Confinement of fire-damaged columns.


 The Sint Pieterschurch in Galmaarden, Belgium was built back in the 13th century. In 1772 she was enlarged and completely renovated in 1995. In 2008 the church was almost completely destroyed by a fire (possibly ignited by fireworks).

Architect Karel Breda, together with Triconsult NV, did the analysis of the damage and coordinated the urgent conservation and consolidation works, executed by Building NV ( Herentals, Belgium).

The stone columns needed strengthening by injection of cementitous grouts..

Before injection , the columns were wrapped with C Sheet 240 to prevent damage to the columns due to pressure build up or possible “aquaplanning” induced by the grout.

Restauration of the wooden piles and beams of the Westerstaktsel in Ostend-One of the longest wooden piers in the world

The Westerstaketsel in Ostend is one of the longest wooden piers in the world (650 meter long, constructed in 1888) and in need of repair to secure the stability. The wooden piles and beams have been repaired with the Aslan, GFRP rebars in combination with epoxymortars. So less new tropic wood needs to be used. And saving our forests.

Self Healing agent, Basilisk, for concrete basin

Water basin repairs itself due to Self-healing Concrete

A water basin of Port of Rotterdam has been constructed with special concrete walls. Due to addition of Basilisk Healing Agent to the concrete the walls will be able to heal itself when cracking occurs. The system is based on bacteria which, when subjected to water contact, will precipitate limestone which will gradually seals the cracks. The technology has been developed at the TU Delft and has been applied in practice due to the corporation of BAM Infra and Basilisk. Available on exclusive base in Belgium through Fortius, Diest

The basin is tank constructed out of four concrete walls. The basin has a length of 47 meters, a width of 5.5 meters and a height of 5 meters. Two walls has been constructed with plain concrete, whereas the other walls has been constructed with the addition of Basilisk Healing Agent.

During the construction there has been no noticeable difference observed in the workability of the Self-healing concrete mixture compared to the plain mixture. Also tests show that there has been no significant difference in the strength development comparing both mixtures (mixtures where identical except the addition of the Self-healing additive).
