The EcoLock System Advantages The Pietrucha Group is the global leader in manufacturing and distribution of high quality EcoLock vinyl sheet piling broadly used in the civil engineering sector in land and water infrastructure investments. Durable, resistant and water-tight solution 50-year limited guarantee. Do not require maintenance as they retain parameters perfectly. Highly resistant to corrosion and the impact of atmospheric and biological factors,including UV radiation, extreme temperatures and sea water. Resistant to mechanical damage, including scratches, cracks and abrasions....

The EcoLock System Application Sheet pilings and cut-off walls with a system of stays In order to protect the banks of different water reservoirs or rivers they can be used with a special system of stays and anchors, providing additional protection and increasing the durability of the system. Taking into account their complete resistance to biological and atmospheric factors, as well as mechanical damage, PVC sheet piling may be used in a wide range of civil engineering projects. The EcoLock sheet piling used in place of steel retaining walls reduces the costs of installation and materials....

The EcoLock sheet piles are manufactured using the extrusion molding method as monolithic profiles or the co-extrusion molding method, with the core made from the material obtained from PVC construction recycling, covered with a layer of...

The EcoLock vinyl sheet piles have various profiles and uses, but all are made of the same highest-quality raw material which determines the physical and mechanical parameters of the product.

The EcoLock System Installation This method is used in cases of very compact or cohesive soil where the force of vibration hammers is not sufficient to embed the vinyl sheet piling to the required depth. Jetting consists in exerting pressure directly under the sheet piles which are being installed, which helps loosen and remove the soil or the obstacles. Special water or air ejectors are used in this technology. This method is used when the constructed walls are not embedded too deeply into the ground and it consists in the PVC piling being installed in a ditch which is subsequently filled...

Case study: Europe’s largest investment using vinyl sheet piles One of the most important functions of the vinyl sheet piling is to prevent the flood-protection systems against water corrosion caused by ground water. The project: Delivery of approximately 72 400 m2 (15690 rm length, which is almost 16 kilometers) of vinyl sheet piling used to construct the anti-filtration barrier in the project „Flood Protection of the polder Gardna V-VI”. The objective: ■■ Protection against water corrosion of the embankment of polder Gardna. ■■ Extension of the filtration route of groundwater. ■■ Increase...
