If you want a reliable supplier of filling sand, sharp sand that can deliver at least 50trips per day depending on the location of your site, then I'm your best option.
The last project I completed, I used 16 China trucks to deliver multiple trips in a single day.
I can work with more than 40trucks on your project. However, this all depends on how fast you make up your mind to work with me. Other projects require the use of the same trucks, so if you contact me today, I'd make an exception for you.
*The price stated does not include cost of delivery. So, you'd need to organize for your truck to come to my dredging pit and I'd load it up for you.
