  1. What about a creek bank that’s approx 10-15 feet high at a 45 degree angle. The erosion is to a critical point. Help

  2. Boulder retaining walls ..no one puts any type of drainage behind em. OR put any tie back's to secure.
    Hold them 🤷‍♂️🤷‍♂️🥺🥴

  3. Sadly, it seems you make a point to insult people from Poland for a laugh. Why? 
    I'd advise you to consider this video as a first off, pre-edit. Good material, sub-par presention.

  4. I know nothing but seems like the failed contractors are thinking that putting the large face out it creates an angle that helps gravity push into the back soil. Wrong of course but seems to make sense for a mind missing important information

  5. U SAID IN UR VIDEO TO FOLLOW U ON INSTAGRAM BECAUSE 90% OF EVERYTHING U DO NEVER MAKES IT TO YOUTUBE!!! I LOOKED IN UR DESCRIPTION ON UR VIDEO ACTUALLY SEVERAL OF UR VIDEOS & U HAVEN’T PUT UR INSTAGRAM ACCOUNT IN ANY OF UR VIDEOS SO MY QUESTION IS WHAT IS UR INSTAGRAM ACCOUNT SO I CAN FOLLOW U BROTHER!!! UR VIDEOS ARE SO EDUCATIONAL & LIKE U TOLD THE CONCRETE GUY U OR HIM CANNOT DO EVERY JOB EVERYWHERE THATS WHY U DO THE VIDEOS NOW I KNOW U ALSO MAKE A LITTLE MONEY FROM DOING THESE VIDEOS & POST THEM!!!!! & I WANTED TO TELL U THANK U FOR DOING THAT FOR US WEEKEND WARRIORS! THANKS A MILLION GOD BLESS & LOVE YA BROTHER

  6. Thanks, for sure, for sharing your expertise. There's more happiness in giving than receiving says the second most knowledgeable person in the universe. Have a great day

  7. Thank you for this information. I believe I have a failing rockery wall along our driveway. Sigh,…the soil between the boulders has eroded away extensively. Now…to get an estimate to fix it…likely not to be a cheap project, 🙁

  8. So if you have a large boulder, with say 6ft by 3ft by 3ft sides, a cheap contractor would create the wall face using the 6ft side and leave 3ft for depth. So I suppose now the rock only offers about half the friction strength plus the pressure from the soil and water has double the surface area to push on (ie pushes on 6ft by 3ft area instead of 3ft by 3ft).
    Very interesting stuff! Thanks

  9. Hi my 18 inch high retaining wall is not doing well.. high clay content in soil and filter fabric so soil is falling into parallel driveway – they did not put drainage in – I need to have it redone – also neighbour has high hedge on boundary behind ( 2 -3 ft higher than my property) Contractor only put in one row of boulders at 18 inch high …maybe I double height of wall by putting extra row of boulders ..but first put gravel drainage – would about 4 – 6 in deep be ok … input please? am I on right track? the videos help a lot…

  10. I bought a house in a condominium and they did a retaining wall. That looks horrible and feels so dangerous. I just posted a video there, you guys can take a look and give me your opinion.
    I wonder if its supposed to be like that, not the uglier side of it. I mean structurally.
    Have a great day. Thanks.

  11. I know I am several years late but, in the midst of much good information pertinent to an immediate job of mine…I loved the intermission. Semper Fidelis!
