We have now created a value-productive method to employ this technological know-how in Bangladesh, which has previously been analyzed and demonstrated efficient in a variety of initiatives. Pile foundation grouting has actually been productively applied in Pakshey Bridge, Rupsha Bridge, Jamuna Bridge, and Padma Bridge under the supervision of foreign engineers applying international equipment and resources. Beneath the Management of Professor Dr. Engineer Md. Jahangir Alam, FCD have formulated a pile foundation grouting technologies utilizing locally made resources in a lower Expense, enabling the rise of pile capability by two times and ensuring seismic resistance of pile foundation.

By using Techno Metal Submit's helical piles, it is possible to sense confident that your structure will sit on the safe and very long-Long lasting foundation.
